to say that a few years ago, installing Windows 7 under the UEFI BIOS is not a difficult task, as long as you turn off the security boot, use legacy mode, and choose a good disk mode. But now manufacturers have found that UEFI can personalize the place is too much, began a variety of toss, made with the domestic mobile phone ROM, like a strong personality but can be modified for everyone's options are less and fewer, unless the manufacturer can provide full-featured BIOS, otherwise install Windows 7 basically No.
Next, the method provided by the small series, but also for the full functionality of the UEFI BIOS products (motherboard or notebook), before the installation of the best in the Advanced BIOS review, if the optional project is limited, peace of mind with Windows 8/10 don't bother (especially the brand notebook computer BIOS).
For the last 5 years, the motherboard or notebook computer with UEFI BIOS can be modified with a U disk for Windows 7 installation:
First of all to prepare 64-bit Win7 ISO image file (32-bit completely does not support EFI), using UltraISO software, such as Win7 ISO to write U disk (select the ISO, the interface above the select "Boot-write hard disk image").
Note that you must format the U disk in Fat 32 format when making the Startup disk.
Then, under the normal Windows 8/8.1 or Windows 10 operating system, locate the Bootmgfw.efi file, which normally exists under the C:windowsbootefi folder.
Rename it to Bootx64.efi, copy to make the Win7 installation disk X:efiboot folder can be (x represents U disk letter, if the U disk does not have this folder, press this name to create a new folder).
Then in the need to install Windows 7 on the computer to insert a U disk, the boot press a variety of shortcut keys (according to the motherboard or brand settings, F2, F10, Del, etc., the general boot will be displayed at the bottom of the screen), into the motherboard BIOS, the security boot (safe boot), and select UEFI mode USB disk boot can start installation of Windows 7.
The name of the option is not the same for each motherboard or brand notebook BIOS, you must be patient with the description on the right
If you're using an EFI motherboard or using a UEFI laptop, you'll need more prep work.
Copy the Bootmgfw.efi mentioned above and the Shell.efi files that need to be extracted from the Windows 8/10 installation disk (or search the Web for download) directly to the USB disk root directory that you just made.
Then, in the need to install the Windows 7 computer BIOS, locate the EFI shell loaded from the file or similar options.
When the computer shows the EFI Shell to start the interface, with Fs0:, FS1:, FS2: To find a U disk letter command.
After entering the installation of U disk, enter the LS command to view the content, when you see the "Bootmgfw.efi" file, execution can enter the Windows 7 installer.
This method is relatively troublesome, we must have patience Oh ~
By the right, using UEFI to install Windows 7 You must use a GPT partition, which you have pushed before. Don't bother to search the direct point of this passage!
